Application filed September 3, 1906.

To aZZ whom it may concern:

Be it known that LHAWLEY PETriBoNE, a citizen of the Cudahy, in, the county of Milwaukee and State .ofllVisconsin, have invented certain new and useful Improvements in Qharging evices for Suction Gas-Producers, of which the following is'aspecification,

to the accompanying drawing.

This invention relates. to charging hoppers for suction gasproducers. Such hoppers are usually provided with bottoms having holes adapted to register with a ertures or holes in the feeding end of thefue magazine of the producer furnace, and with tight-fitting closures or covers. The ho or is so supported that it may be rotated to a limited-ex: tent in order to bring the openingsin the botom into register with those in the end of the fuel magazine when it is desired to feed the furnace, and to carry them out of register, thereby closing the openings into the furnace chamber, when feeding is not desired. It is important that there should never be a direct opening or communication between the external air and the interior of the furnace, as such opening would result in dilution of the gas deli ered born the producer, and render in the rnace or proncer, owing to the formation of an explo sire mixture or" air with the inflammable gases being produced.

My invention has for its object to produce a special locking mechanism for a charging hopper arranged to prevent the simultaneone opening the cover or closure of the opper proper, and the communicating pasbetween the hopper and fuel chamber of the producer or furnace.

portion of the producer furnace, wherein there is charged theiuel from which the gas is made. v e upper end of this chamber is closed byacover plate a through which are a number of openings (1.

v The feed orcharging hopper is designated as a whole B. It has a; closeiitting cover G pivoted at c tothe walls oi the hopper. Upon this pivot the cover is adapted to swing, so that the hopper may be opened for filling with fuel. When in closed position a catch 0 carried by the cover engages with a pin or lug d and holds the cover tightly in pl The hopper is provided with a bota plate It, in which are formed brought into register with the. openings a in the cover plate a of the producer furnace.

he hopper is adapted to rest upon the u per end of the producer and to be partially rotated thereupon, in the usual manner, to

unperforated tively as the hopper is turned. these rotary movements of provided with handles F, and

usual construction, and are not in themselves novel with me.

' 2 represents a lug projecting fromthe edge or periphery of the cover C of the hopper, its location being preferably contiguous to the pivot c.

This latter part may be a lug or'a rim or flange extending outward from the side wall of the ho per. Y

6 is a s iding bolt mounted in. 4 and in an aperture 7 or lug opper near its lower end. rounds the bolt 6, hearing at one enoagainst the lug 8, and at its ot ier end lar 10 secured to the stem .s'pring being normally under tending to lift the bolt, to enter the openings 4 brought into register.

11 is a stop'pln carried bythe bolt and arthe bolt the tension and causingits up er end and 3 when t iey are he parts thus far described may be of per with fuel it ber below,

ranged to engage with the underside of the part 5 of the hopper, and thereby limit the u pwa'rd movement of the bolt.

12 is an aperture formed in a flanged or projecting part of the'cover of the furnace or producer, and arranged in line with the bolt 6.

13 is a handle'projecting from the bolt by which it is manipulate The normal positions of the parts of the locking device, comprising the bolt 6', are in dicated in Figs. 2 and 3. From this it will be seen that the cover C is tightly closed upon the end of the hopper, in which position'the aperture 3 in the cover stands opposite the end of the bolt, so that the spring 9 will slide it into and through such aperture, thus positively locking the cover in closed osition. Under these circumstances the op er is free to be rotated either to open or to c ose communication with the fuel chamas the lower end of the bolt is lifted so high as to be entirely withdrawn from the a )erture 12 in the cover of the producer cham er, and above the to 1 plate (1 thereof.

When it becomes desirable to fill the hopis necessary to turn the cover upon its pivot to open its upper end. This, however, cannot be done until the bolt 6 is moved to unlock the cover, and this in turn cannot take place until the parts are brought to the position indicated in Fig. '1, that is to say, the hopper as a whole must be rotated until the openings 0 and a are out of register and communication between the hopper and the fuel magazine of the producer is. entirely out off. When in this position the lower end of the bolt,--which it will be understood turns with the hopper is brought directly opposite to the aper'ture'12 in the top plate or the producer.- The bolt may now be forced down, compressing the spring 9 carrying its lower end into the aperture 12, and withdrawing/its upper end from the, aperture 3, the handle 13 being used to elfect t' his movement of the bolt. Nhen the parts assume this position the hopper as a whole is locked against rotation relative to the producer, and the cover of the hopper is free to turn on its pivot. As soon as the cover is turned, even to a slight extent, the aperture 5% is. carried out of the latter is held down bythe flange or projecting part 2 of the cover, thus maintaining the hopper locked to the roducer so long as the cover is moved from t e closing position.

From this description, tion with the drawings, it will be seen that it is impossible to simultaneously open the upper end of the hopper, and communication etween the hopper and the fuel chamber.
